For the first time in a long time, I’m at a loss for words. But I suppose if I have to say something about the following exclusive clip from Monday’s season finale of Castle, it’s: wow.

Any fan of the ABC crime drama knows that episodes that find Beckett chasing info about her mother’s murder are always a highlight, and this year’s season finale is no exception. There’s always a new, shocking reveal waiting for the audience when this issue is brought up, and emotionally, it’s always a hot button issue for Castle and Beckett, particularly because Castle knows that Beckett tends to become dangerously obsessed with the case. Earlier this season, her infatuation was accompanied by a mysterious warning given to Castle: She’s getting too close to the answer – or, as Castle puts it in the clip, “If you don’t stop, they will kill you, Kate.”

Torn by his loyalty to his more-than-a-friend and his desire to keep her safe, Castle is forced to lay a lot of cards out on the table in Monday’s episode. And. I. Can’t. Wait.

It will surprise me if you’ve gotten this far in the text without pressing play already, but in case you haven’t, I invite you to do so below! And make sure to watch Castle’s season finale on Monday at 10 p.m. ET.
